Sevice engine soon!
I mean Service........Ok, Im driving on a back road. About 30 minutes driving maybe more maybe less. Constant speed anywhere from 40 to 80... All the sudden the service engine soon light comes on. This started after I had headers installed on my car. Any reason? This happens any time in this situation.
Anyone have this happen or any ideas?
Thanks

Car: 1986 Trans Am, 1991 Firebird
Engine: 355 TPI, 3.1L V6
Transmission: 700R4 in both
Here's an idea. Find out the trouble code and let us know. Unless we know what trouble code the ECM is throwing then we have no way to help you. If I had to guess though I'd say it has something to do with your O2 sensor.
------------------
1986 Trans AM
355 TPI
4 Wheel Disc Brakes
9 bolt Borg Warner Rear (2.77's....oh joy) :P
6" rods, approx. 9.7:1 Compression, Stock TPI (soon to be ported), 24#/hr LTI injectors (cleaned and flowmatched by Cruizin Performance), Hedman Shorty Headers, 3" exhaust with 80 series flowmaster, SBC 993 heads completely redone and modified for 1.6 RR, 1.52 RR (for now), Comp Cams XE262-14 TPI Cam, Holley AFPR, TPIS airfoil, MSD wires, MSD 6-AL Ignition, Hypertech 53,000 volt coil.
Track times to come.

Since I don't know the trouble code that you have this is just a guess. It could be this infamous TBI intermittent EGR code. I get this on occasion in the RS when I am cruising at a constant speed on the highway. Checked the system, nothing wrong with it. Supposedly, from what I've heard, it has to do with a glitch in the less than brilliant L03 PROM. Something about how it doesn't recoginze that EGR occuring. If its a code 32 and it only happens rarely, then the above explanation it probably the cause.
